This mouse was grown from its mother's skin cells
K. Hayashi/Kyushu University For the first time, researchers have grown eggs entirely in a lab dish. Skin-producing cells called fibroblasts from the tip of an adult mouse’s tail have been reprogrammed to make eggs, Japanese researchers report online October 17 in Nature. Those eggs were fertilized and grew into six healthy mice. The accomplishment could make it possible to study the formation of gametes — eggs and sperm — a mysterious process that takes place inside fetus..>> view originalTaikonaut duo blasts off for China's longest space mission
China's space agency launched two astronauts, or taikonauts, Monday morning into low Earth orbit aboard its Shenzhou 11 spacecraft. If all goes according to plan, in two days they will dock with China’s Tiangong 2 space station, where the taikonauts will stay for 30 days to test its habitability and to carry out medical and scientific experiments.Monday’s launch marked the sixth time China has sent taikonauts into space, and the beginning of the country’s longest crewed mission yet as it builds..>> view originalThe Universe Has At Least Two Trillion Galaxies: Why Is The Finding Important?
First Posted: Oct 18, 2016 06:01 AM EDT There are at least two trillion galaxies up there. Image used for representation only. (Photo : Bill Ingalls / NASA / Getty Images) The size of the universe is incomprehensible, and now the sheer scale of it has become even more unfathomable after a recent study suggested there are 10 times the numbers of galaxies as previously believed. According to astrophysicist Christopher J. Conselice from England's University of Nottingham, the universe has a..>> view originalPeru investigates death of 10000 Titicaca water frogs

Europe is on track to achieve an epic Mars landing on Wednesday (Oct. 19) — that is, as long as its spacecraft can survive supersonic speeds, iron-melting heat and a tightly choreographed set of final maneuvers. The landing capsule, named Schiaparelli, is scheduled to touch down on the Red Planet's surface tomorrow (Oct. 19) as part of ExoMars 2016, a joint mission by the European Space Agency (ESA) and Russia's Roscosmos space agency.

After encountering engine troubles on Sunday, NASA researchers have adjusted Juno’s orbit plan.The probe was originally scheduled to fire up its main rocket on Wednesday, reducing its orbital period around Jupiter from 53 days to just 14. Officials chose to initiate the “period reduction maneuver” (PRM) in order to study Juno’s fuel pressurization system, but technical difficulties forced them to postpone.“Telemetry indicates that two helium check valves that play an important role in the firin..>> view originalThe amazing sweating robot
At 5 1/2 feet tall, its face fixed between a grin and a grimace, the humanoid robot Kengoro is something of a synthetic Arnold Schwarzenegger. That is not to say the machine, created by the University of Tokyo’s JSK laboratory, is a recursive time-traveling assassin. Rather, Kengoro is a sweaty beefcake among metal bipeds. The average two-legged machine does not have Kengoro’s stamina. For a svelte robot, Kengoro is strong, powered by 108 motors. Thanks to this large number of motors plus a u..>> view originalOrbital ATK's Antares Rocket Returns to Flight with Gorgeous Night Cargo Launch
WALLOPS ISLAND, Va. — We have liftoff! For the first time in two years, an Orbital ATK Antares rocket has successfully launched into space, departing NASA's Wallops Flight Facility here this evening (Oct. 17) on a mission to deliver supplies to the International Space Station (ISS). The upgraded Antares rocket soared into the night sky at 7:45 p.m. EDT (2345 GMT) today, topped with Orbital ATK's uncrewed Cygnus cargo capsule.

This is not an election year in which it is easy to get attention, unless your name rhymes with Gump. Nevertheless, it's worth taking note of a colorful, contentious, and counterintuitive political drama playing out in the top left corner of the country. It’s a fight happening within the left, and like a great many such fights in US politics these days, it reveals sharp differences over how to make progress in the face of Republican intransigence. In this case, the subject is climate change pol..>> view original
